Description
Die Erfindung betrifft ein Verfahren sowie eine Einrichtung zum Bewegen von Punkturnadeln entsprechend dem Oberbegriff der Ansprüche 1 oder 3.The invention relates to a method and a Device for moving pin needles accordingly the preamble of claims 1 or 3.
Durch die DE 38 10 439 C1 ist ein aus Schneidzylinder,
Punktur-, Sammel- und Falzmesserzylinder sowie aus einem
Falzklappenzylinder bestehender Falzapparat bekannt,
mittels welchem ein zwischen dem Schneidzylinder sowie
Punktur-, Sammel- und Falzmesserzylinder einlaufender
Papierstrang an seinem Anfang durch auf dem Punktur-,
Sammel- und Falzmesserzylinder angeordneten Punkturen
aufgenadelt, durch Schneidmesser des Schneidzylinders in
Verbindung mit auf dem Punktur-, Sammel- und
Falzmesserzylinder in der Nähe der Punkturen
angeordneten Schneidleisten geschnitten, die Signaturen
auf dem Punktur-, Sammel- und Falzmesserzylinder
transportiert bzw. gesammelt, transportiert und
nachfolgend dem Falzklappenzylinder übergeben werden.
Diese Punkturen bestehen u.a. aus mehreren in axialer
Richtung hintereinander auf einer Steuerspindel
schwenkbar in Punkturhalterarmen angeordneten
Punkturnadeln. Diese treten mit ihren Nadelspitzen zum
Aufnadeln des Produktes entsprechend den
Produktionserfordernissen aus der Peripherie des
Punktur-, Sammel- und Falzmesserzylinders heraus, indem
die zylinderfest gelagerte Spindel mittels eines
Kurvengetriebes verdreht wird. Dabei beschreiben die
Nadelspitzen der Punkturnadeln einen Teil einer
Kreisbahn um die Rotationsachse der zylinderfest
gelagerten Spindel.From
Nachteilig bei diesen Punkturen ist es, daß die Punkturnadeln verhältnismäßig weit von der Schneidleiste angeordnet sind, um eine Kollision mit der Schneide des Schneidmessers zu verhindern. Ein großer Abstand zwischen einem Trennschnitt der Papierbahn und der in die Papierbahn einstechenden Punktursysteme ist hinsichtlich des Papierverschnittes dann von Nachteil, wenn wie beim Akzidenz- oder Telefonbuchdruck, ein mit Punkturlöchern versehener Randstreifen nach erfolgter Produktion wieder abgeschnitten werden muß.A disadvantage of these punctures is that the Puncture needles relatively far from the cutting bar are arranged to collide with the cutting edge of the To prevent cutting knife. A great distance between a separation cut of the paper web and in the Paper web puncturing puncture systems is regarding the paper waste is disadvantageous if, as with Commercial or phone book printing, one with dot holes provided edge strips again after production must be cut off.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren sowie eine Einrichtung zum Bewegen von Punkturnadeln an der Peripherie eines Zylinders zu schaffen, mittels welchen ein Einstich in einen Produktstrang nahe der Schneidlinie eines gegen eine Schneidleiste wirkenden Messers ermöglicht wird.The invention has for its object a method and a device for moving pin needles to create the periphery of a cylinder by means of which a puncture into a product strand near the Cutting line of one acting against a cutting bar Knife is made possible.
Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil der Ansprüche 1 oder 3 genannten Merkmale gelöst.This object is achieved by the im characterizing part of claims 1 or 3 Features resolved.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß zwischen den Punkturlöchern und der Schnittkante des Druckproduktes ein geringer Abstand besteht, ohne daß die Punkturnadeln den Schneidvorgang behindern. Dies ist insbesondere bei Telefonbuch- und Akzidenzdruckmaschinen von Vorteil, da bei der nachfolgenden Bearbeitung der Signaturen dann ein schmalerer Randstreifen abgeschnitten werden kann und somit ein Papierverlust reduziert wird. Weiterhin ist von Vorteil, daß bei Abgabe der Signaturen von einem Punktur-, Sammel- und Falzmesserzylinder, nachfolgend als Transportzylinder bezeichnet, auf einen Falzklappenzylinder für das bei der Abgabe an den Falzklappenzylinder noch auf dem Transportzylinder befindliche und von den Punkturnadeln gehaltene Ende ein Bewegen der Punkturnadelspitzen in die Rückzugsrichtung des Signaturendes erfolgt, was das "Abnadeln" der Signaturen, d. h. das Zurückziehen der Punkturnadeln erleichtert, so daß ein Schlitzen von Punkturlöchern, ein Beschädigen von Punkturnadeln oder ein Herausziehen der Signaturen aus den Falzklappen des Falzklappenzylinders vermieden wird.The advantages that can be achieved with the invention exist especially in that between the puncture holes and the cut edge of the printed product a small distance exists without the puncture needles the cutting process hinder. This is particularly the case with phone book and Commercial printing presses are an advantage because the subsequent processing of the signatures narrower edge strips can be cut off and thus reducing paper loss. Another advantage is that when the signatures are submitted from a puncture, collecting and folding knife cylinder, hereinafter referred to as a transport cylinder on a Folder cylinder for that when delivered to the Folder cylinder still on the transport cylinder end located and held by the puncture needles Move the needle points in the retreat direction the end of the signature is what the "needling" of the Signatures, d. H. the retraction of the puncture needles relieved, so that a slitting of puncture holes, damage to puncture needles or pulling them out the signatures from the jaws of the Jaw cylinder is avoided.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is in the Drawing shown and will be described in more detail below described.

Ein Transportzylinder 1 ist über stirnseitig angeordnete
Seitenscheiben 2 (zweite Seitenscheibe nicht
dargestellt), sowie nichtdargestellte Achszapfen in
nichtdargestellten Seitengestellen gelagert und weist
sich in achsparalleler Richtung erstreckende Traversen 3
auf. Jede Traverse 3 trägt eine Nutleiste 4, welche an
ihrer in Richtung Peripherie 6 des Transportzylinders 1
gerichteten Seite eine Schneidleiste 7 aufnimmt, auf
welche ein Schneidmesser 8 eines nichtdargestellten
Schneidzylinders einwirkt, d. h. zwischen welchen ein
strangförmiges Produkt 24 geschnitten wird. Auf einer
seitenscheibenfest gelagerten Steuerspindel 9 ist ein
Punkturhalterarm 10 festgeklemmt, an dessen freiem Ende
11 ein Punkturnadelhalter 12 formschlüssig angeordnet
ist. Der Punkturnadelhalter 12 weist an seinem
peripherienahen Ende 13 eine Punkturnadel 14 auf. Der
Punkturnadelhalter 12 ist an seinem punkturnadelfernen
Ende 16 mit einem Antrieb 17, z. B. einem Hubmagneten
verbunden. Dabei ist die Punkturnadel 14 in einem Stößel
29 befestigt, welcher eine Stößelführung 31 aufweist,
die mit dem Hubmagneten in Verbindung steht. Im
Ruhezustand wird der Stößel 29 mit der Punkturnadel 14
gegen die Kraft einer Druckfeder 32 in eine in Richtung
Antrieb 17 gerichtete Endstellung gedrückt. Die von der
Traverse 3 getragene und an den Seitenscheiben 2
befestigte Nutleiste 4 weist jeweils einen Durchbruch 18
für jeden Punkturhalterarm 10 auf. Es sind entsprechend
den Erfordernissen mehrere Punkturhalterarme 10,
Punkturhalter 12 sowie Punkturnadeln 14 in der
vorbeschriebenen Art voneinander beabstandet auf der
Steuerspindel 9 angeordnet. Die Steuerspindel 9 ist
zumindest an einem Ende fest mit einem
nichtdargestellten Rollenhebel verbunden, welcher mit
einer seitenscheibenfesten Steuerkurve in kraft- oder
formschlüssiger Verbindung steht. Die Steuerspindel 9
ist als Hohlspindel ausgebildet, nimmt in ihrem Inneren
eine Drehstabfeder 21 auf, welche an einem Ende drehfest
mit der Hohlspindel verbunden ist und am anderen Ende an
der Seitenscheibe befestigt ist, wodurch der Rollenhebel
stets an die Steuerkurve gedrückt wird. Die Punkturnadel
14 kann infolge der Bewegung des Punkturnadelarmes 10
durch einen in achsparalleler Richtung verlaufenden
Schlitz 22 aus der Peripherie 6 des Transportzylinders 1
heraustreten. Der Schlitz 22 kann durch herausnehmen
einer Abdeckleiste 23 verbreitert werden (Fig. 1).A transport cylinder 1 is arranged on the front
Side windows 2 (second side window not
shown), as well as not shown axle journal in
Storage and not shown side frames
traverses extending in the axis-parallel direction 3
on. Each traverse 3 carries a
Während der Produktion läuft ein Produktstrang 24 in der
angegebenen Produktionsrichtung D zwischen dem
nichtdargestellten Schneidzylinder sowie dem
Transportzylinder 1 ein, wobei der Produktstrang 24
mittels der Punkturnadeln 14, die sich noch in einer
Mittelstellung B befinden, aufgenadelt und nachfolgend
von dem gegen die Schneidleiste 7 des Transportzylinders
1 wirkenden Schneidmesser 8 quergetrennt wird. Vor dem
"Aufnadeln" vollführen die Nadelspitzen 26 nach dem
Durchtritt durch die Peripherie 6 des Transportzylinders
1 aus ihrer Grundstellung A (Fig. 2) infolge einer
kreisbogenförmigen Schwenkbewegung E des
Punkturhalterarmes 10 von E1 nach E2 eine ansteigende
Kurve 36 zu einer Mittelstellung B (Fig. 1 und 2).
Die Mittelstellung B der Nadelspitzen 26 befindet sich
in unmittelbarer Nähe einer Radialen oder Senkrechten
33, welche die Mittellinie des im Schneidzylinder
befindlichen Schneidmessers 8 zum Zeitpunkt des
Schneidens des Produktstranges 24 darstellt. Nach
erfolgtem Querschneidvorgang des Produktstranges 24
durch das Schneidmesser 8 und dem beginnenden
Auseinanderbewegen der Punkturnadeln 14 und der Spitze
des Schneidmessers 8 vollführen die' Nadelspitzen 26 der
Punkturnadeln 14 jeweils eine lineare, nahezu radiale
Bewegung F des Stößels 29 von F1 nach F2 bis zu ihrer
Endstellung C, wobei die Nadelspitzen 26 nach dem
Verlassen der Peripherie 6 ihren weitesten Weg
zurückgelegt haben. Durch diese lineare Bewegung F der
Punkturnadeln 14, d. h. von F1 zu F2 (Kurve 37 nach
Fig. 2) von der Mittelstellung B nach der Endstellung C
wirken auf die Produkte nur geringe zusätzliche Kräfte,
wodurch ein Schlitzen der Punkturlöcher vermieden wird. During production, a
Desgleichen wird in der Endstellung C der Punkturnadeln
14 nach dem Vollzug des zweiten Trennschnittes durch den
Produktstrang 24 eine so entstandene Signatur 27 gegen
ein selbständiges "Abnadeln" auf dem Transportzylinder 1
geschützt.
Die bereits beschriebene lineare Bewegung F der
Nadelspitzen 26 von der Mittelstellung B in die
Endstellung C erfolgt in etwa radialer Richtung zum
Transportzylinder 1, d. h. etwa in einem Winkel Alpha
von 20° zur Radialen oder Senkrechten 33. Die lineare
Bewegung F wird durch die magnetische Betätigung der
Stößelführung 31 bewirkt und verläuft in Richtung einer
Rotations- oder Längsachse 34 der Punkturnadel 14. Zur
Abgabe der Signaturen 27 an einen anderen Zylinder eines
Falzapparates, z. B. an einen Falzklappenzylinder, wie
in der DE 38 10 439 C1 dargestellt, weist der
Transportzylinder 1 nichtdargestellte Falzmesser auf.
Nach Ausbildung des Querfalzes und bei der übernahme des
noch von den Punkturnadeln 14 auf dem Transportzylinder
1 gehaltenen Endes der Signatur 27 werden die
Nadelspitzen 26 der Punkturnadeln 14 von der Endstellung
C in die innerhalb der Peripherie 6 des
Transportzylinders 1 liegende Grundstellung A, d. h. von
F2 nach E1 zurückgefahren, ohne dabei die Mittelstellung
B zu durchlaufen (Kurve 38, Fig. 2). Dabei verläuft die
Kurve 38 annähernd als Gerade mit einem mittleren Winkel
Beta von etwa 40° zur Radialen oder Senkrechten 33
(Fig. 2). Somit wird dieses Ende der gefalzten Signatur
von den Punkturnadeln 14 freigegeben. Dabei erfolgt
durch die Überlagerung der Bewegung E des
Punkturhalterarmes 10 sowie der Bewegung F des Stößels
29 als teilsprialförmige Bewegung nicht nur ein Rückzug
der Nadelspitzen 26 unter die Peripherie 6 des
Transportzylinders 1, sondern gleichzeitig ein Bewegen
der Nadelspitzen 26 in die Rückzugsrichtung des Endes
der bereits gefalzten Signatur, also entgegen der
Drehrichtung des Transportzylinders 1. Somit ist die
Umfangsgeschwindigkeit der Punkturnadeln 14 während
dieses Zeitraumes reduziert, was eine qualitätsgerechte
Übergabe des Druckproduktes an einen anderen Zylinder
sichert.Likewise, in the end position C of the
The already described linear movement F of the
Die Betätigung des Antriebes 17, z. B. eines Hubmagneten
kann mittels am Transportzylinder 1 befindlichen,
nichtdargestellten Stromzuführungen, z. B. Schleifringen
erfolgen.The actuation of the
Die Nadelspitzen 26 der Punkturnadeln 14 legen ab ihrem
Austritt aus der Peripherie 6 des Transportzylinders 1
bis zur Maximalstellung C der Nadelspitzen 26 einen Weg
von fünf bis 15 mm, vorzugsweise elf Millimetern bei
dicken Produkten, gemessen in radialer Richtung des
Transportzylinders 1 zurück. Ein radiale Entfernung von
der Grundstellung A zur Mittelstellung B der
Nadelspitzen 26 entspricht zwei Drittel der radialen
Entfernung der Nadelspitzen 26 von der Grundstellung A
zur Maximalstellung C. The
Bei einer anderen Ausführungsvariante ist es möglich,
den Antrieb 17 als Umkehr-Hubmagneten auszubilden. Der
Umkehr-Hubmagnet weist zwei Schaltstellungen auf, so daß
eine Druckfeder 32 für die selbsttätige Rückstellung des
Stößels 29 entfallen kann.In another embodiment variant, it is possible to
form the
Bei weiteren Ausführungsvarianten kann der Antrieb 17
als beliebiger Linearantrieb ausgeführt sein, so z. B.
